Del BaileyOsteoporosis usually causes no symptoms until a bone breaks. It is a disease where bones lose density and mass, or their structure changes, so they get weak and break more easily. A bone density scan can find it early, and treatment mixes food, exercise and, for people at higher risk, prescription medicine.

I have spent years around people who train hard and assume strong muscles mean strong bones. They are two different tissues. Muscle lets you know when it is tired. Bone says nothing, which is exactly why this disease gets caught late. Most of us never think about our bones at all until something goes wrong.
What Is Osteoporosis?
The National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) says osteoporosis is a bone disease where density and mass drop, or the structure changes, which raises the chance of a break. NIAMS lists these as risk factors:
- Being female, older or slender-framed
- A parent with osteoporosis or a hip fracture
- Low estrogen after menopause or low testosterone in men
- A diet low in calcium and vitamin D, or dieting too much
- Long-term use of glucocorticoids (steroid medicines) and some other drugs
- Not moving much, heavy drinking and smoking
Osteoporosis Symptoms to Watch For
NIAMS calls osteoporosis a silent disease because there are usually no symptoms until a bone breaks. Bones can break from a small fall or from everyday strain like bending, lifting or coughing. Breaks in the spine can cause bad back pain, loss of height or a stooped posture called kyphosis. A hunched back is a late sign. It is not an early warning, so waiting for it is the wrong plan.
How Osteoporosis Is Diagnosed
The Mayo Clinic describes the bone density test as a DXA (or DEXA) scan. It uses low-dose X-rays to measure how much mineral is in your bones, usually at the hips and spine. You lie on a padded table while a scanner passes over you, and it does not hurt. If you have several of the risk factors above, ask your clinician whether a scan makes sense for you. Anyone who has skipped a checkup because they felt fine knows how easy it is to take no news as good news, and with a silent disease that habit is the thing to watch.
Osteoporosis Prevention: Calcium, Vitamin D and Exercise
NIAMS lists these steps to protect your bones: weight-bearing exercise such as walking, drinking alcohol only in moderation, not smoking, taking prescribed medicines, and eating a diet rich in calcium and vitamin D.
The plain old advice is still good advice: get moving. Exercise is not everyone’s cup of tea, and that is fine, because a regular walk is on the list too. Women are at higher risk, but men get osteoporosis as well, so this is not only a women’s issue.
The NIH Office of Dietary Supplements sets the calcium RDA (Recommended Dietary Allowance) at 1,000 mg a day for men aged 51 to 70, and 1,200 mg for women 51 and older and men 71 and older. The upper limit is 2,000 mg a day for adults 51 and older. For vitamin D, the RDA is 600 IU (15 mcg) for ages 19 to 70 and 800 IU (20 mcg) from age 71, with an upper limit of 4,000 IU (100 mcg).
Vitamin D helps your gut take in calcium, and we have a piece on vitamin D in winter if you want more. Supplements are a less settled question than food. The FDA has approved a health claim that calcium and vitamin D supplements may reduce the risk of osteoporosis, but the NIH notes that not all studies have found they improve bone health or cut fractures. The U.S. Preventive Services Task Force concluded that daily doses under 1,000 mg of calcium and 400 IU of vitamin D do not prevent fractures in postmenopausal women, and that the evidence on larger doses is not strong enough to say. Ask your clinician before starting one. Anyone who has stood in a pharmacy aisle looking at a wall of supplement bottles knows how confusing it gets.
Osteoporosis Treatments Doctors Prescribe
The Mayo Clinic says bisphosphonates are the most common prescription medicines for osteoporosis in people at higher risk of fractures. They include alendronate (Fosamax, Binosto), risedronate (Actonel, Atelvia), ibandronate and zoledronic acid (Reclast). Medicine is only one piece of the plan. Food, movement, and staying away from smoking and heavy drinking count too.
Other options Mayo lists:
- Denosumab (Prolia): a shot under the skin every six months. Its bone density results are similar to or better than bisphosphonates.
- Teriparatide (Forteo): a daily injection that builds bone, for up to two years.
- Romosozumab (Evenity): a monthly injection at a healthcare office, for one year at most.
- Estrogen and raloxifene (Evista): hormone-related options. Mayo notes estrogen can raise the risk of breast cancer and blood clots.
Which medicine suits you depends on your risk of breaks, your other health conditions and the drugs you already take, so that choice is up to your clinician. Most of us have gone to an appointment with a list of questions and forgotten every one the second we sat down, so write yours down first. Being careful in daily life is just common sense. Osteoporosis is something many people learn to live with, and finding it early gives you more to work with.
Osteoporosis Symptoms and Treatments FAQ
What are the first signs of osteoporosis?
There usually are none. NIAMS calls it a silent disease because symptoms usually show up only when a bone breaks, sometimes from a small fall or a cough. A break in the spine can cause back pain, loss of height or a stooped posture. A bone density scan is how doctors find it before a break.
How is osteoporosis diagnosed?
With a DXA scan, according to the Mayo Clinic. It uses low-dose X-rays to measure the mineral in your bones, usually at the hips and spine. You lie on a padded table while a scanner passes over your body, and it does not hurt. Your clinician decides who needs one.
How much calcium and vitamin D do adults need?
The NIH sets the calcium RDA at 1,000 mg a day for adults 19 to 50, and 1,200 mg for women 51 and older and men 71 and older. Vitamin D is 600 IU a day for ages 19 to 70 and 800 IU from 71. Food counts toward both totals.
What medicines treat osteoporosis?
Mayo Clinic lists bisphosphonates such as alendronate and zoledronic acid as the most common. Other options are denosumab, teriparatide, romosozumab, estrogen and raloxifene. Each has different dosing and risks. A clinician matches the medicine to your own risk of breaks and health history.
